Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Solar is an important part of NESO’s ambition to run the grid carbon zero by 2025.
The amount of sunlight that strikes the earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year. Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.
Solar cells, also known as photovoltaic cells, convert light energy directly into electrical energy. They are made primarily from semiconductor materials, with silicon being the most common. When sunlight strikes the surface of a solar cell, it excites electrons in the semiconductor material, creating an electric current.
There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).” Solar PV relies on a natural property of “semiconductor” materials like silicon, which can absorb the energy from sunlight and turn it into electric current.
In the United States, heating, ventilation and air conditioning (HVAC) systems account for 30% (4.65 EJ/yr) of the energy used in commercial buildings and nearly 50% (10.1 EJ/yr) of the energy used in residential buildings. Solar heating, cooling and ventilation technologies can be used to offset a portion of this energy.
The initial step in the process of solar energy conversion involves the absorption of sunlight by the photovoltaic (PV) cells within a solar panel. These cells, constructed from semiconductor materials such as silicon, capture photons from sunlight. When these photons strike the PV cells, they excite electrons, thereby creating an electric current.
How Is Electricity Stored From Solar Panels?
The Importance of Energy Storage in Solar Power Systems 1. Balancing Energy Supply and Demand. Day-Night Cycle: Solar panels generate electricity only when the sun is shining, but energy demand often continues after sunset.Batteries store excess energy produced during the day for use at night or during cloudy periods.
